Multi-colored vehicle rear lamp

ABSTRACT

A lamp for the rear of a vehicle is disclosed with a light transmissive cover having a red first illuminated surface area and a clear second illuminated surface area. It has a first LED light emitter located directly beneath the red first area, a second LED light emitter located directly beneath the clear second area, and a third LED light emitter, also located directly beneath said clear second area. The third red LED light emitter is for emitting red light through the clear second area simultaneously with light transmitted through the red first area, whereby the first and second areas are adapted to collectively form a contiguous red illuminated surface area.

BACKGROUND

The present invention relates to lamps, an more specifically to suchlamps used on the rear of vehicles.

Rear lamps on vehicles are governed by regulations, in the U.S. andother countries. These include, for example in the U.S.A., 49 C.F.R.Sec. 571. These may generally include one or more requirements regardingcandela, illuminated surface area, placement, and other attributes,normally grouped by various function or location. The Federal MotorVehicle Safety Standard, FMVSS 108, in Part 571.108 of the Code ofFederal Regulation Title 49, specify that vehicles over 2032 mm wide arerequired to have stop lamp with a lens area (Effective ProjectedLuminous Lens Area (EPLLA)) of at least 75 square centimeters. Othervehicles EPLLA requirements vary. The area for cars need be at least 59square centimeters. A circular stop lamp used on a large trailer todaywill be approximately 10 cm in diameter or about 78.5 square cm of area.This may be met, for example, with a standard nominal 4 inch or 10 cmdiameter circular lamp, meaning the housing is also circular and has adiameter of about ten (10) centimeters (or about 4 to 4½ inches), orwith an oval shaped lamp, meaning that the housing is also oval. Thesize and shape of such oval housing may vary, but a typical example maybe an oval with dimensions of about 2½ inches tall and about 6¾ incheswide. As shown here it is desirable to meet illuminated surface arearequirements or goals while providing an arrangement that is more spaceefficient. Various stop-tail-turn (STT) lamps used LEDs with a largelamp with separate cavities or other areas, such as one cavity for theSTT functions and another for other functions, such as a dedicated whiteLED backup light. Other LED STT lamps use additive chromatic effects toalter color patterns. Also, separate dedicated lamps, such as separatewhite LED back-up (or reverse) lamps, have been used. While eachapproach has various pros and cons, they do not provide the arrangementsand advantages of the present claimed designs.

Thus, there is a need for improvement in this field.

DESCRIPTION OF THE SELECTED EMBODIMENTS

For the purpose of promoting an understanding of the principles of theinvention, reference will now be made to the embodiments illustrated inthe drawings and specific language will be used to describe the same. Itwill nevertheless be understood that no limitation of the scope of theinvention is thereby intended. Any alterations and further modificationsin the described embodiments, and any further applications of theprinciples of the invention as described herein are contemplated aswould normally occur to one skilled in the art to which the inventionrelates. One embodiment of the invention is shown in greater detail,although it will be apparent to those skilled in the relevant art thatsome features that are not relevant to the present invention may not beshown for the sake of clarity.

Referring to FIGS. 1-11E, some examples of the invention are shown. Notethat one such example, as shown in FIGS. 1-5, illustrates an ornamentaldesign for a vehicle lamp as shown. In that regard, optionally portionsof the “front” of such lamp installed lamp (FIG. 2) may be shown inphantom lines, being normally out of sight when that portion of thatlamp is mounted on a vehicle.

Various examples are shown with similar reference figures, but with thehundred's digit prefix otherwise varied. Hence, in the drawings FIGS.1-7 show lamp 100, FIGS. 8A and 8B show lamp 200, FIGS. 9A and 9B showlamp 300, and FIGS. 10A and 10B show lamp 400. Otherwise, the referencecharacters in the ten's and one's digits, when the same, are the same orsimilar. These illustrate, a lamp 100, 200, 300, 400 for the rear of avehicle (not shown). The lamp includes a light transmissive cover havinga first illuminated surface area 1, 101, 201, 301, 401 and a secondilluminated surface area 2, 102, 202, 302, 402. The first area of thecover is light transmissive and red in color. There is one or more firstLED light emitter 110, 210, 310, 410 located directly beneath the firstarea of the cover. Normally, one or more such first light emitters isred in color, but other optional colors, such as white, or colorcombinations are optional.

The second area 2, 102, 202, 302, 402 of the cover is also lighttransmissive and is clear in color. Moreover, there is one or moresecond light emitter 120, 220, 320, 420 located directly beneath theclear second area. The second light emitter comprises an LED that emitswhite light. Alternatively, the second light emitter may comprise anemitter, such as an LED, that emits amber light, such as for exampleupon the activation of a turn indicator.

Additionally, one or more third light emitter 130, 230, 330, 430 locateddirectly beneath the clear second area. The third light emitter emittingcomprises an LED for emitting red light through the clear second areasimultaneously with light transmitted through the red first area,whereby the first and second areas are adapted to collectively form acontiguous red illuminated surface area. The lamp does not have motorsor moving parts. The covers, and their first and second areas, and theLEDs are fixed and non-movable.

FIGS. 11A-E show, conceptually, some various illumination combinations.These are not the only possible combinations, and merely are examples.The reference character convention therein has power source, P₁, P₂, P₃,such as electricity and/or their controller(s). When such power sourceis activated, in FIGS. 11A-D, it is shown encircled. Upon activation,one or more of the light emitters, L₁, L₂, L₃, such as LEDs, emit light.Cover 1 (red) and cover 2 (clear) are shown, covering in the Z-axis, thevarious light emitters. Upon activation, one or more of the lightemitters, L₁, L₂, L₃, cause red light R₁, red light R₃, and/or whitelight W₁, to be emitted from the lamp. Alternatively, white light W₁ maybe substituted with (or also have in addition) an amber light (notshown). For example, the shading of the first area and/or the secondarea, in FIGS. 8A-10B, indicate red light emitted from that area. Thus,for example, the conceptually illumination shown in FIG. 11A correspondsto the red illuminated shading of only first red areas 201, 301 and 401in FIGS. 8A, 9A and 10A, respectively. And, for example, theconceptually illumination shown in FIGS. 11D and/or 11E corresponds tothe red illuminated shading of both first red areas 201, 301 and 401 aswell as red light from second clear areas 202, 302 and 402 in FIGS. 8B,9B and 10B, respectively.

While the example of FIGS. 1-7 shows six first light emitters (three oneach of two sides), two second (white) light emitters, and two third(red) light emitters, more or less of each may be used. Also, there maybe more than one red first area(s) and/or more than one second cleararea(s) of the cover of the lamp. Also, other non-LED light emitters,such as incandescent bulbs or other devices that emit light may besubstituted, although the preferred designs use LEDs.

Optionally, the lamp is a stop-tail-turn lamp for a vehicle and whereinthe sum of the first illuminated surface area 101, 201, 301, 401 and thesecond illuminated surface area 102, 202, 302, 402 is at least fifty(50) square centimeters, and more preferably is at least seventy-five(75) square centimeters and less than 100 square centimeters, and morepreferably is less than 85 square centimeters. However, other collectiveilluminated surface areas are possible, per 49 C.F.R. § 571.108, such asfor a stop lamp for a motorcycle at least 5000 square millimeters (andpreferably, but optionally, less than 8,000 square millimeters). Forother vehicles less than 2032 millimeters in overall width, for stoplights in a single or combined compartment light, the collectiveilluminated surface area preferably is at least 5000 square millimeters(and preferably, but optionally, less than 8,000 square millimeters).

Optionally, the various emitters are activated upon one or more variousevents. For example, optionally the lamp may have the white second lightemitter 120, 220, 320, 420 is activated upon the vehicle being placed inreverse. Optionally, although not normally, the red third light emitter130, 230, 330, 430 may be de-activated upon the vehicle being placed inreverse. Preferably, however, such second and third light emitters areon concurrently (see e.g. FIG. 11E). Also, optionally, the red thirdlight emitter 130, 230, 330, 430 is activated upon the vehicle braking.More commonly, however, as discussed below regarding light intensity,the first and third emitters, both normally red, are both activated intail lamp mode, and are still activated, but emit brighter light, duringbraking or stop mode. Likewise, even if the headlamps are off and/or thefirst and third lamps are otherwise not in tail lamp mode, duringbraking or stop mode preferably they are activated and of the brighter,stop lamp, intensity.

Optionally, the lamp may comprises a fourth light emitter (not shown)located directly beneath the clear second area 2, 102, 202, 302, 402and, wherein the fourth light emitter comprises an LED that emits amberlight. This may be used for a flasher and/or turn signal, emitting lightfrom the clear second area. For example, the amber LED is in that caseactivated upon the corresponding turn signal (left or right) beingactivated.

A variety of shapes and sizes (in addition to the area ranges above) ofthe lamp are possible. For example, optionally, the lamp is shaped froma group consisting of: a circle (including optionally a circle with adiameter of about 10 centimeters)(FIGS. 8A, 8B, 10A, 10B); and, an oval(FIGS. 1-7, and in particular FIG. 1). It may be square, elliptical,rectangular (FIGS. 9A and 9B), irregular, or otherwise. Typically, thelamp will have a housing, such as housing 106, and one or more circuitboards, such as circuit board 107.

Optionally, the lamp has no reflector(s), such as for example, parabolicreflector(s), and no barrier wall(s) between the first light emitter(s)and the third light emitter(s) (see e.g. FIGS. 6, 7 and 11A-E).Optionally, not having such reflector(s) and/or walls may pertain asbetween the first and second light emitter(s) and/or between the secondand third emitter(s). The reverse is also true in that, optionally, onemay include reflector(s) and/or barrier walls between any of suchcombination(s) of light emitters.

Optionally, the lamp may be a single compartment lamp or may be amultiple compartment lamp.

Also, optionally the intensity of the various emitted light(s) may bevaried. For example, the red light from area 101, 201, 301, 401 (and/orfrom area 102, 202, 302, 402) may be lower intensity in tail light mode,when the vehicle head lamps are activated, and higher intensity whenbraking. The red first light emitter and the red third light emitter mayoptionally each be activated upon the vehicle head lamps beingactivated. Also, the red first light emitter and the red third lightemitter optionally may each emit brighter light upon the vehiclebraking. Such intensity may, for example, be achieved by poweringadditional light emitters and/or by controller the amount of power tothe light emitters (by resistors, diodes or otherwise) in the first area101, 201, 301, 401 and/or area 102, 202, 302, 402. Other features, asare conventional, may of course be provided such as power conductors 108(FIG. 7) and otherwise.
